You're probably a more evolved spirit, than I am. I'm on the brink of chucking a project at Warner because I don't like dealing with people who rush-rush you to get back to them with negotiation details, then blow you off for two days because...well, apparently just because.
Phone's rung with two other projects that I declined because I was waiting on this character. Screw him; next show calls, I'm taking it. Let him find someone else with the 'perfect for our project skill set and equipment fit' about which he was so enthusiastic, 72 hours ago.
I get those all the time. People call and want info immediately, and then they tell me they'll call me the next day or so. I get a call a week or a few weeks later and they want me to shoot the next morning. I tell them I have a shoot either way.
